That's not a bad thought. Under the right circumstances, such as a relatively high gravitational field and vacuum, as on the Moon, this might be the preferred engine.
Note that power is an external input. It's going to take a lot of power to operate the superconducting magnets, and to power the RF generators and antennae.
I'm thinking that this kind of device could lead to a truly multi-mode rocket engine, taking in atmospheric gases and heating them for rocket exhaust, then when transitioning to near space using the VASIMR system, and finally settling down to a low-thrust long-duration system for the long haul.
Is denial of denial a sign of denial?
A not so random thought:
Will “was stupid” be a quote will remember Obama for or a summary of his administration.
It popped into my head as part of a dream.
But it was one of the most bizarre dreams so far.
Still digesting it.
Attempting to create a 3d model in Wings 3d of Bradamante.
Or, what I see the ship to be in my minds eye.
Probably won’t get far, as my skills with 3d stink, but I’ll try.
